Brazing technology allows metallurgical joining of dissimilar materials by use of a filler material. In this paper, brazing technology applied to casing connections is presented. The brazing process, or temperature/torque/time (TTT) process, is performed with regular casing connections, a filler material deposited by flame spray, and a flux. Two processes were developed, one for expandable-grade material (VM50) and one for quenched-and-tempered-grade material.
Introduction
Casing connectors continue to be a potential liability in complex wells that use premium connections or expandable liners.
